I'm on the cusp here. I can either shove more money into Canon gear or switch platforms (motly to gain high ISO performance and low-light AF).
Vey ist mir!

If you are not in a rush I suggest you wait until these cameras are actually in the hands of the public and full unbiased reviews are released.
I am sure they are all super cameras with their own strengths and weaknesses. And I quite sure the differences between them are probably not that much in the end. A bit like high end APO telescopes.
Canon 1Dx, Nikon D4, Canon 5D mark iii and Nikon D800 are so close in specs it really comes down to what you want to use it for.
1DX on paper sounds the better camera over the D4 but 5D mark iii and D800 isn't so clear. Its high MP high resolution versus low light performance otherwise the differences between the 2 cameras is miniscule. Also low light performance of each has to be verified. There are both good and weak examples of low light high ISO images for both cameras now. Nikon has a good track record as being the stronger of the 2 camera makers with regards to low light. But physics is physics and 36mp and 4.88 micron pixels (which are larger than the 7Ds by the way) should mean the 5D mark iii would be better in that regard. But if you are shooting landscapes the higher MP in normal daylight would be better. If shooting in low light then the 5D sounds the better. Action shots the 5D would be better. Neither is going to replace your Astro CCD camera anyway. Rightly or wrongly I am drawn to the 36mp with near medium format resolution for $3000 (the cheapest medium format camera is a Pentax 645 and its about $11,000). Low light autofocus though would be an easy win for the Nikons which are rated to F8 and the Canons to F5.6.
It seems the high end DSLR market is becoming quite specialised. 1DX may be best all round camera for all uses like it was intended except for size, weight and cost. 5D mark iii seems more of a superb all pupose camera. The sample images though lack the wow factor of the sample D800 images by a long way in my opinion if that comes at the cost of fast frames per second (which I wouldn't use hardly ever) but I would prefer excellent low light performance but its not a deal breaker in my case. I am sure either would outperform my 40D (which is excellent).
The other factor of course is lenses. You need to make up your own mind about these and which ones are better than others from each maker and which ones you would use. Novoflex adapters make them somewhat interchangeable between brands but you lose autofocus and automatic aperture control and image stabilisation.
